System.List property with escaping the comma (,)

Summary

How would we escape a comma (,) in the System.List Component

Content

So the scenario is that the user has been mailed and our bot would check if the mail is received. 

The user can answer with the following options in the System.List component.

1. Yes

2. No, but please sent it again

3. I need to change my student number

As you can see, option 2 contains a comma (,). In the current situation this leads to 4 options in the menu (instead of 3):

Yes
No
but please sent it again
I need to change my student number

See the snippets what I tried so far.. Will keep on trying, but hopefully someone else has a bright idea.
